90-120 / 1000+ resultsresearch Effects of progesterone (P4) and estrogen (E2) on fertilization failure and early embryonic mortality in superovulated cows
Hormonal treatments affect cow fertility and early embryo development.
research [PRACTICAL EXPERIENCES WITH OVULATION INHIBITION].
Ovulation inhibitors effectively treat menstrual issues and improve fertility but can have side effects.
research [Clinical findings with a low-dosed antiandrogene (cyproteronacetate) and aethinyloestradiol women with virilising symptoms (author's transl)].
The treatment improved acne, seborrhoea, and hirsutism, with some side effects like spotting and nervousness.
research In vivo and in vitro exposure to free fatty acids induce increased androgen production in animal models: a potential pathogenic factor of the polycystic ovary syndrome
Free fatty acids may increase androgen production, potentially contributing to polycystic ovary syndrome.
research Association of a polymorphism in the ornithine decarboxylase gene with male androgenetic alopecia
research An intergenerational androgenic mechanism of female intrasexual competition in the cooperatively breeding meerkat
Androgens in female meerkats influence aggression and dominance, affecting social dynamics and offspring behavior.
research Neuroactive steroids induce changes in fetal sheep behavior during normoxic and asphyxic states
Neurosteroids help protect fetal brains from asphyxia damage.
research Animal Models and the Developmental Origins of Polycystic Ovary Syndrome: Increasing Evidence for the Role of Androgens in Programming Reproductive and Metabolic Dysfunction
High levels of androgens during early development may cause PCOS-like symptoms.
research An adolescent girl presenting with primary amenorrhea: A case report of complete androgen insensitivity syndrome
A 15-year-old girl with no menstrual period was diagnosed with a genetic condition that makes her body unable to respond to male hormones, leading to female characteristics despite having male genetic makeup.
research Effect of Neurosteroid Withdrawal on Hippocampal GABA‐A Receptor α4‐Subunit Expression in Female Mice
Neurosteroid withdrawal increases α4 subunit expression in the hippocampus, which may relate to catamenial epilepsy in women.
research Effect of finasteride on ovulation induction in nonresponder (hyperandrogenic) polycystic ovary syndrome (PCOS) women
research Androgen Profiling by Liquid Chromatography–Tandem Mass Spectrometry (LC-MS/MS) in Healthy Normal-Weight Ovulatory and Anovulatory Late Adolescent and Young Women
The research found that anovulatory young women have higher androgen and hormone levels than those who ovulate, suggesting immature hormonal regulation rather than a specific condition.
research An Unusual Cause of Primary Amenorrhea
The 18-year-old girl likely has a condition called müllerian agenesis, which caused her to not have a uterus and experience no menstrual periods.
research Virilizing Ovarian Tumor in a Postmenopausal Women
research Hyperandrogenism in a postmenopausal woman: a rare case of ectopic adrenal cortical gland
A postmenopausal woman's excess male hormone symptoms were caused by a rare adrenal gland tissue in her ovary.
research Dimorphic regulation of the MafB gene by sex steroids in hamsters (Mesocricetus auratus)
Sex steroids affect the MafB gene differently in male and female hamsters.
research Supraphysiological Dose of Testosterone Impairs the Expression and Distribution of Sex Steroid Receptors during Endometrial Receptivity Development in Female Sprague–Dawley Rats
High doses of testosterone disrupt hormone levels and receptor expression in the uterus, affecting fertility.
research Problems in evaluating chronic toxicity of contraceptive steroids in dogs
High doses of some contraceptive steroids cause health issues in dogs, but their relevance to humans is unclear.
research Contrast-Enhanced Ultrasound (CEUS) Evaluation of Canine Prostatic Hyperplasia before and after Osaterone Acetate Therapy: Preliminary Results
Osaterone acetate reduces prostate size and enzyme levels in dogs with benign prostatic hyperplasia.
research A prospective study examining isolated acne and acne with hyperandrogenic signs in adult females
Acne in adult women may occur alone or with signs of high male hormones.
research Disorders of ovulation
Ovulation disorders are a major cause of infertility and menstrual problems in women.
research Equine alopecia areata: a retrospective clinical descriptive study at the U niversity of C alifornia, D avis (1980–2011)
Horse alopecia areata is rare and mainly affects their appearance.
research Inhibitory influence of agmatine on catamenial-like seizure susceptibility in progesterone withdrawn female rats
Agmatine may help reduce seizures linked to hormone changes in female rats.
research Activation of extrasynaptic δ-GABAA receptors globally or within the posterior-VTA has estrous-dependent effects on consumption of alcohol and estrous-independent effects on locomotion
δ-GABAA receptors affect alcohol consumption based on the estrous cycle and influence movement regardless of the cycle.
research Epidermoid Cyst in the Bitch Mammary Gland
An epidermoid cyst in a dog's mammary gland is rare and benign.
research Alterações morfométricas, estereológicas e funcionais no epidídimo e parâmetros de fertilidade em ratos tratados com finasterida
Finasteride impairs sperm quality and fertility in rats, even after stopping treatment.
research Alopecia attributed to neoplastic ovarian tissue in two ferrets.
Hair loss in two ferrets was caused by ovarian tissue tumors, not adrenal issues.
research Effects of Testosterone on the Expression of Connexin 26 and Connexin 43 in the Uterus of Rats During Early Pregnancy
Testosterone changes important cell communication proteins in pregnant rats' uteruses, which might affect pregnancy success.
research Chemical Characterization and Ameliorating Effect of Centratherum anthelminticum Extract against Polycystic Ovary Syndrome in Wistar Rats
Centratherum anthelminticum seed extract effectively treats Polycystic Ovary Syndrome in rats.
